The following is done in a loop:
•
•
Code is running out of RAM.
•
All I/O pins are left unconnected.
•
All the communication peripherals are exercised in loop-back mode.
•
USB – Only logic is exercised by loading and unloading FIFO.
•
µDMA does memory-to-memory transfer.
•
DMA does memory-to-memory transfer.
•
VCU – CRC calculated and checked.
•
FPU – Float operations performed.
•
ePWM – 6 enabled and generates 150-kHz PWM output on 12 pins, HRPWM clock enabled.
•
Timers and Watchdog serviced.
•
eCAP in APWM mode generates 36.6-kHz output on 4 pins.
•
ADC performs continuous conversion.
•
FLASH is continuously read and in active state.
•
XCLKOUT is turned off.
